Well, well, well........I've been trying to log into this site since I got home with my 425 the beginning of September!!!!
My 2 cents on your bucket question is,,,,,,,,if you can afford it, get them both. I did and haven't regretted it once. I would suggest not getting the small bucket, but large bucket holds 10 cubic feet vs. 7 for the 4in1 bucket. I have excavated in excess of 300 cubic feet of material from under my house, which is now up in the air 4 feet so that I can put a full foundation under it, and have used the large bucket exclusively. The 4in1 is wonderfully versatile and has been used a lot in the neighborhood for material movement and placement......nothing like having a tractor to make friends in the neighborhood!! I have used the 4in1 to place stones in a stone wall, move railroad ties for a retaining wall, pull a 25' deep well point out of the ground, pull up 4x4 posts out of the ground to name only a few. I bought a toothbar for it from Markham Welding which makes it even for flexible.
If you can get only one bucket, I would recommend the 4in1, but I'm glad I have both........
